Title: 겨ㄹ상시 지락보호 가능한 누전차단기
Filed: 1998-12-31
Abstract: 본 발명은 부하에 공급되는 교류 전원이 부하 기기의 절연 열화 및 인체의 감전등으로 인하여 누전이 발생될 경우에 자동적으로 전원을 차단하여 안전사고의 발생을 미연에 방지하는 누전 차단기에 관한 것으로서, 특히 접지측 인입선 단선에 의한 결상시에도 단선과 동시에 누전 차단기를 트립(TRIP)시켜 안전사고가 발생되지 않도록 한 결상시에도 지락보호가 가능한 누전 차단기를 발명한 것이다. 
     상기한 바와 같이 누전 차단기는 누전시 두 선로에서 각각 발생하는 자계의 세기의 차이를 검출 전원을 차단하는 것이나 일반 누전차단기는 결상시에는 누전 차단기가 동작되지 못함으로 개폐기가 계속 온 상태로 유지하게 된다. 
     그러므로, 접지측 선로가 단선되어 결상되었을 경우에 단선되지 않은 다른 선로는 계속 부하에 연결되어 전압이 인가되어 있게 된다. 
     이때 이 부분에 지락이 발생하더라도 누전 차단기는 이를 검출하지 못하여 동작하지 않으므로, 누전 발생시 화재가 발생하고, 인체의 접촉시에는 감전사고가 발생되는 등의 안전사고가 발생하는 문제점이 있었다. 
     본 발명은 상기한 바와 같은 종래의 누전 차단기의 문제점을 해결하기 위해 발명한 것으로서, 접지측 인입선 단선으로 인한 결상시에도 단선과 동시에 트립코일이 동작하여 전원 개폐기가 개방 전원을 차단함으로서 지락사고가 방지되게 한 것이다. 
     이 경우는 단선된 인입선을 다시 연결시켜야만 재투입이 가능하게 되어 일반 누전 차단기와 같이 동작하게 할수 있는 누전차단기로 복귀되게 하는 누전 차단기로서 접지측 인입선단선에 의해 결상된 경우 접지측인입선 단선과 동시에 전원이 차단됨으로 비접지측 인입선 부위의 절연불시로 말미암아 누전 전류에 의한 지락사고 및 그 부위에 인체가 접촉되더라도 감전사고는 일어나지 않는다. 이 경우 누전차단기 그 원래의 기능을 발휘하게 하려면 단선부분을 접속시킨후, (SS)를 재투입해야 한다.

IPC: C12N15/09
Filed: 1996-07-24
Abstract: Coat color is important to the pig breeding industry for a number of reasons. It is therefore desirable to develop populations of pigs which will breed true for coat color. However, establishing such populations would be time-consuming and costly using traditional test mating programs. It is therefore desirable to determine the coat color genotype of individual pigs. The inventors have shown that the KIT gene in pigs is involved with coat color determination. Specifically, the inventors have discovered that the difference between the I, IP, and i alleles of the coat color determining gene is duplication of at least part of the KIT gene in the I and IP alleles. Further, the inventors have discovered that the difference between the I and IP alleles is that, although both I and IP have a duplication in the KIT gene, only I and not IP exhibits a deletion in one of the duplicated regions. These discoveries have allowed the inventors to develop methods for distinguishing between the alleles I, IP, and i, thereby determining the genotype of individual pigs with respect to coat color. In accordance with the present invention, there are provided methods for determining the genotype of individual pigs with respect to coat color and kits for use in carrying out such methods.

The auxiliary coil is wound on the primary coil, and the primary coil is wound on the auxiliary coil. When the wound coil reaches a predetermined number of turns, the secondary coil is wound. When the secondary coil reaches a predetermined number of turns, the residual primary coil and the auxiliary coil are wound in turns. The auxiliary coil is wound on the primary coil.
